anita has two sisters and three brothers. the mean of all their ages is 6 years. what will their mean age be 10 years from now?t
pogonyaev
Answer:
Now: 6 yr mean age
in 10 yrs? 16 yr mean age
in 20 yrs? 26 yr mean age

Why?  Because regardless of the relationship between each sibling's age, your always adding the 10yrs to each individual, which you are then dividing out to determine the mean age.  See proof below:

Including anita, there are 6 people.  We'll define each age as an unknown variable.  Assume we know nothing about the relationships between their ages

for example sake
anita's age = a
sister 1's age = b
sister 2's age = c
brother 1's age = d
brother 2's age = e
brother 3's age = f

Now:
mean age = (a + b + c + d + e + f)/(6 people) = 6 yrs

in 10 yrs:
mean age = ((a+10) + (b+10) + (c+10) + (d+10) + (e+10) + (f+10))/(6 people)
mean age = (a + b + c + d + e + f + 60)/(6 people)
mean age = (a + b + c + d + e + f)/(6 people) + (60)/(6 people)
mean age = (a + b + c + d + e + f)/(6 people) + 10

Notice the first term is the same expression of the mean age for "Now"
Thus, in 10 yrs:
mean age = 6 + 10 = 16 yrs

The same principle applies for "x" yrs from now, as long as we know what the mean age is "Now"

What is the abscissa of the midpoint of the line segment whose endpoints are (5, 2) and (2, 2)?
Masteriza [31]

Answer:

Midpoint is (3.5, 2)

Step-by-step explanation:

the midpoint of the line segment whose endpoints are (5, 2) and (2, 2)

To find midpoint of two end points we use formula

(\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})

(5, 2) , x1 = 5  and y1= 2

(2,2), x2=2  and y2= 2

Plug in all the values and find the midpoint using the formula

(\frac{5+2}{2},\frac{2+2}{2})

(\frac{7}{2},\frac{4}{2})

(3.5, 2)

So midpoint is (3.5,2)

Which two points should the line of best fit go through to best represent the data in the scatterplot?
dedylja [7]

Answer:

B. (1, 16) and (6, 1)

Step-by-step explanation:

These make the most since because one is at the peek of the graph and the other one is at the bottom of the graph, also, these two points are on opposite sides of the graph.
